Display apparatus and image display method thereof

1. A method of displaying images on a display apparatus, the method comprising: performing a slideshow displaying a plurality of images including a first image and a second image in a first order on a screen of the display apparatus automatically, wherein the first image has a lower part and an upper part, and the second image has a lower part and an upper part, the upper part of the first image being adjacent to the lower part of the second image; when a rotation by 180 degree of the display apparatus is detected, rotating each of the plurality of images displayed on the screen by 180 degree so that each of the plurality of images can be shown in its original orientation and the lower part of the first image is adjacent to the upper part of the second image, and resuming the slideshow displaying the rotated plurality of images in a second order on the screen of the display apparatus, wherein the second order is the reverse direction of the first order.

2. The method as claimed in claim 1 , wherein the resuming the slideshow displaying the rotated images in the second order comprises displaying a list of thumbnail images corresponding to the images along with the images on the screen of the display apparatus for a predetermined time after the detecting the rotation.

3. The method as claimed in claim 2 , wherein the predetermined time is set by a user.

4. The method as claimed in claim 2 , wherein a display location of the list of the thumbnail images changes corresponding to the rotation.

5. The method as claimed in claim 2 , wherein the list of thumbnail images scrolls in a direction corresponding to the second order.

6. The method as claimed in claim 1 , further comprising: performing another slideshow displaying the images on the screen of the display apparatus simultaneously with performing the slideshow; and changing an order of the other slideshow in correspondence with the change in position of the display apparatus.

7. A display apparatus comprising: a display unit which displays images on a screen; a rotation detector which detects a rotation of the display apparatus; and a controller which controls the display unit to display a slideshow displaying a plurality of images including a first image and a second image in a first order automatically, and, wherein the first image has a lower part and an upper part, and the second image has a lower part and an upper part, the upper part of the first image being adjacent to the lower part of the second image, and when a rotation by 180 degree of the display apparatus is detected by the rotation detector, the controller rotates each of the plurality of images displayed on the screen so that the lower part of the first image is adjacent to the upper part of the second image, and resumes the slideshow displaying the rotated plurality of images in a second order on the screen of the display apparatus, wherein the second order is the reverse direction of the first order.

8. The display apparatus as claimed in claim 7 , further comprising: a signal processor which processes the images, wherein the signal processor provides an interface through which a user sets a time, and the controller sets the time as the predetermined time.

9. The display apparatus as claimed in claim 8 , wherein the controller controls the signal processor and the display unit to display the list of thumbnail images in a changed location corresponding to the rotation.

10. The display apparatus as claimed in claim 8 , wherein the controller controls the signal processor and the display unit to scroll the list of thumbnail images displayed on the displayed unit in a direction corresponding to the order in which the images are displayed on the display unit.

11. The display apparatus as claimed in claim 7 , further comprising: another storage unit that stores other images, wherein the controller arranges the other images stored in other storage unit in a third order, arranges the other images stored in the other storage unit in a fourth order corresponding to the change in position in response to detection of the change in position by the position change detector, and controls the signal processor to process the other images in an order corresponding to the third order or the fourth order wherein the display unit displays the other images in the order processed by the signal processor simultaneously with the images.

12. A display apparatus comprising: a position change detector which detects whether a change in a position of the display apparatus occurs; a storage unit which stores a plurality of images including a first image and a second; a display unit; a controller which controls the display unit to display a slideshow of the plurality of images including the first image and tile second image in a first order automatically, wherein the first image has a lower part and an upper part, and the second image has a lower part and an upper part, upper part of the first image being adjacent to the lower part of the second image, wherein the controller rotates each of the plurality of images so that the lower part of the first image is adjacent to the upper part of the second image and controls the display unit to display the slideshow of the rotated plurality of images in a second order if the position change detector detects the change in position while the slideshow of the plurality of images is displayed in the first order, wherein the second order is different than the first order, wherein the controller changes at least one of a display location and an orientation of the plurality of images displayed on the display unit corresponding to the change in position.

13. The display apparatus as claimed in claim 12 , wherein the controller controls the display unit to display a list of thumbnail images corresponding to the images, together with the slideshow of the images in the second order, for a predetermined time after the position change detector detects the change in position while the slideshow of the images is displayed in the first order.
